Hi, first, I’m sorry for the pain that your experiencing. Before proceeding with surgery on the lumbar spine; L4-L5; make sure to see a neurologist, and get a EMG
( electromyogram ).. if you’re experiencing numbness, you can have compression on the nerve, which if severe, can cause paralysis . See Mayo’s page on Peripheral neuropathy.
I had my done, and the neurologist said, “ok, we need to operate… Tomorrow, or you may never walk again” now that was a long time ago, and the best thing I could offer is to do your due diligence. Take care of yourself and stay active!! 🙏🙏🙏
